Ingredient Notes:

  • Gluten Free Flour Blend – I tested this recipe with I have tested this recipe with King Arthur Measure for Measure GF and Bob’s Red Mill 1 to 1 GF blend. That doesn’t mean others will not work; I just have not tested other flours.
  • Xanthan or Guar Gum – If your flour blend doesn’t have one of these binders, you will need to add one teaspoon.
  • Butter – Use unsalted butter, room temperature, or slightly melted.
  • Eggs – Size Large.
  • Vanilla Extract – This recipe can use pure vanilla extract or imitation.
  • Halloween Candy – I love using Snickers, Almond Joy, York Peppermint Patties, Mounds, M&Ms, Junior Mints, Butterfingers, Candy Corn, and Heath Candy Bars. Click on any of the candies to see if they are gluten free and which varieties are gluten free.

Recipe Step-By-Step Directions:

Preheat your oven to 350º F and ensure the oven rack is in the middle of the oven.

Step 1: Use a sharp knife to chop up the candy bars on a cutting board. If you are using M&Ms or Reeces Pieces, you don’t have to chop those.

Step 2: Add the dry ingredients to a large mixing bowl and use a wire whisk to blend the ingredients.

Step 3: In a smaller bowl, add the softened butter, eggs, and vanilla extract. Whisk to mix.

Note you can also use a standing mixer with a paddle attachment to make this cookie dough.

Step 4: Add the leftover Halloween candy to the bowl of dry ingredients.

Step 5: Pour the wet ingredients over the dry ingredients and use a large spoon to mix them into soft cookie dough.

Step 6: This is what your cookie dough should look like. You may need to add more liquid using a starchy gluten-free flour blend.

Step 7: Use a cookie scoop to drop dough balls onto a parchment paper-lined baking sheet. Space the cookie dough about 1 1/2 inches apart so the cookies have room to spread when baking.

Step 8: Bake the cookies for 9-10 minutes (depending on the size of the cookies you are making.) Remove them from the oven and cool the cookies on a rack. Remember, melted Halloween candy can be very hot, so do not eat it until it cools down.

Tips and Recipe FAQ:

Can you use candies like Jolly Ranchers and Skittles?

I do not recommend using fruity candies. The flavors don’t work with the buttery sugar flavor of these cookies.

How do you store leftover cookies?

Store these gluten free leftover candy cookies in an airtight container in the refrigerator. They will keep fresh for up to 4 days.

Can you freeze extra cookies?

Yes, you can easily freeze these cookies. Move the cookies to a freezer bag when they are cooled to room temperature. They will keep fresh for up to 5 months.

  • NOTE: You can also use a standing mixer with the paddle attachment.

  1. I used King Arthur Measure for Measure to test these cookies. Other blends should work, but note if your blend is starch-heavy, you may need additional butter.
  2. Use any Halloween candy, but stick with chocolate types and avoid candy like Jolly Ranchers. I used Snickers and Reeces Pieces.
  3. Store these cookies in an airtight container for up to 4 days in the refrigerator. 
  4. Freeze these cookies in a zip-style freezer bag.


Please know that every gluten free flour blend has a different starch to grain ratio. If you use a blend I didn’t test, you may need to adjust your moisture levels in your baked goods.
